2.3 In-Rush Current
The in-rush current should be as shown below.

RCON-EC Max. 40A (Note)
Note: When 4 axes max. of ELECYLINDER are connected
When multiple driver units are used, depending on the capacity of the 24V DC power source, a
voltage drop might occur when the units are turned on.
In the RCON system, the timing can be adjusted with the following two parameters to reduce
the risk of voltage drop due to inrush current. Inrush current lasts for about 5 ms per axis. Adjust
the timing as warranted, within a range such that the offset does not affect operation.
[Driver shutdown release delay time]
The MC parameter is equipped with a function that offsets the release
timing of the drive source cutoff circuit of each driver unit. It offsets the release timing, which
allows it to suppress any possible voltage drops.
•
5 ms per axis has been set for the initial value.
•
The minimum for each axis should be 50ms for the 200V driver unit.
•
The release timing of the drive cutoff circuit for one unit (four axes) should be misaligned for
the EC connection unit.

This parameter adjusts the time from when servo ON command signal SON is input until servo
ON.
By shifting the timing of each actuator, instantaneous power can be suppressed when the servo
ON command is applied at the same time.
[DC Power Supply for Motor Drive (PSA-200)]
The inrush current the DC power supply (PSA-200) for drive a motor are as shown below.
